We show the results of computer simulations of the time scale generated by the atomic time (TA) algorithm, using data obtained from an ensemble of clocks at Communications Research Laboratory (CRL). Three accuracy evaluations were made using the labo

Microwave Rabi Resonances of Cs atom are observed by using optical pumping and optical detection with a laser diode. In case of Δ F=0, π porahzed pumping light, mF=0 atoms remain in the same magnetic sublevel. This result leads to the realization o

The Majorana effect on the hydrogen maser and the cesium (Cs) beam frequency standard is studied. In the hydrogen maser, the Majorana transition is used to the state selection successfully to eliminate the atoms in the [F = 1, mF = 1] state. As the r

In order to set the C field, we use both field-dependent transitions, (F = 4, m F = + 1) → (F = 3, m F = ±1), to control the fluctuation and to compensate the effect of C field uniformity. The side-lobes of these transitions pull the center freque

Initially, beam tube experiments adopted an H-plane-bend Ramsey cavity using an E-plane feed and a solenoid coil to make a uniform C-field [1], [2]. This system is similar to the Cs 1 and 2 atomic clocks at PTB. Thereafter a conventional type E-bend

A simulation of a cesium-beam primary frequency standard, using a beam-trajectory method, is carried out. In the calculations, the following assumptions are made: 1) the beam collimator has a finite area instead of a point source, 2) the effective di
